Application filed August 7, 1902. Serial No 118,784. (No model.) I

To allen/hom it may concern:

Be it known that we, MAX GTTNER, residing and having post-office address at Limbacherstrasse41,Che1nnitz,SaXony,Germany,

and RICHARD BAEGER, yresiding and having This invention relates Ato anapparatus for separating liquids from'solid matter. It possesses over all former devicesof this kind the advantage that it may be used for separating the solid matter from street-sewerage, fecal substances, rinsing-water of closets, and similar materials which on account of their composition impede the separation of the solid parts from the liquid matter, because the watery parts containedin these matters stick extraordinarily fast to the solid ingredients Mash in manufacturing beer also belongs to the above-mentioned mixtures of`matter,'it being well known.

that it has to be cleared by means of a lengthy process. The present apparatus renders it possible to shorten this refining process or to separate the clearing-wort from the draft in a very' short time.

In the accompanying drawings, Figure 1 is ratus, while Fig. 2 represents a plan view and partial transverse section thereof.

Around the vertical main shaft l a number of separating-baskets revolve and at the same time revolve on theirown axes, said baskets being journaled on the main shaft lin a suitable and well-kno'wn manner and consisting,

ber above the annular diskh 3 is divided into several parts by means of perforated plates G, arranged and attached in a radial direction and extending inwardly to the edge of the into the separatingbaskets 2 and terminatesy at its lower-'end in the lower chamber 4 of the separating-basket. take ot' the revolvingr motion of the main shaft 1, and the-separatiug-baskets. 2 rotate with them and also around the pipes/9. Each pipe 9 rests upon peculiarly-formed catching-plate -10,built within the separating-basket 2. This catching-plate is inclined, has the shape of a trough, and is rigidly attached'at one side to the cast-iron revolving disk 12, Fig. 1', by means of a horizontal flange 11, Fig. 2, and its other side has a downwardly-elongated mantle part 13, which projects through the opening 14 of the revolving disk 12. One of the edges 15 of the catching-plate 10 is extended and arranged vertically, and consequently parallel, to the axis of the separating-drum.

.-In Fig. 2 the fourseparating-baskets are singly represented, so that the catching-plates o. represents a top may be distinctly seen. View of the separating-basket and catchingpla-te. In b the catching-plate is removed, while vthe separatingfbasket is represented in complete exteriorview. The opening 1 4 in revolving disk 12 at the bottom of the basket is visible. At c the catching-plate is shown alone, the separating-basket beingcompletely removed. Particular attention is called to the attachment of lthe catching-plate to the revolving disk by means of the borders 11 and 11which are fastened by rivets or screwed and which ou account of the narrow space available are turned outwardly on one side and inwardly on the other. 1n cl both the separating-basket and the catching-plateis shownin horizontal section. The wallsti of the scoopchambers-are perforated or consist of wirework. The separating-baskets are journaled in such a manner that crowns of balls 17 are built within the bottom revolv- ,ing disk- 12 and the covering-disk` 16,` sothat The parts 8 and 9 par' discharges 18 are arranged, one adjacent to each of the fourseparating-baskets 18, as seen in Fig. 1 and in Fig. 2 at b. These tunnels 13 discharge into a chamber built within the fixed frame of the machine, said chamber being closed bythe horizontal cover 19 and comprising cylindrical outer wall-plate 20` and a bottom 2l, which is sloped from its highest point at 2l, Fig. 1, downwardly to the discharge-pipe 22, where the separated liquid passing from the funnel 13 finds outlet.

The system rigidly attached to the main shaft 1 is driven in a well-known manner by means of a belt running upon the pulley 23, while the followingl mechanism, which has been built for the particular purpose ot' the present invention, brings about the radiation of the separating-baskets.

On the nuclei' side of the pulley 23 a leather ring 24, extending laterally from said pulley,

is provided and communicates motion to friction -cone 2 5, formed also of leather disks, through the convex friction-wheel 26. The convex disk 26 rotates around an axis, (indicated by the dashed and dotted line 27,) and a spring 2S, arranged in the same direction of axis, presses the convex disk against both leather cones 2l 25. To vary the speed of rotation of the cone 25, the axis of rotation 27 of the convex friction-wheel is moved around the center 30 to any position by means of the hand-lever 29. When the lever 29 is in the position shown in Fig. 1, the cones 24 and 25 have nearly the same circumferential speed. If the lever 29 is lowered, so as to stand horizontal, the two radii of the convex frictionwheel which decide the speeds of rotation of the cones 2fland 25 will change considerably, and the circumferential speed of 25 will then be smaller than that of 2G. It the lever 29 is furtherlowered until theaxis27 of the convex friction-wheel 26 is in line with the frictioncone 25, the latter will stand still. 'lhus according to the proportions of size of the two friction-cones 24 and 25 and according to the adjusted position of the lever 29 it is possible to give the shaft 3l any desired number of revolutions from zero to a maximum value. A pinion 32, attached to the vertical shaft3l, drives a spur-wheel 33, Fig. 1, which carries a worm 34, F-ig. 2, meshing with the two worm-wheels 35. These latter again are keyed with the worm -wheels 36, which have .the same axis and in turn mesh with the wormwheels 37, and these, 37, are arranged on the same axis with the pinions 38, Fig. 2, which mesh with the spur-gears 39, fixed to the sepmating-baskets 2. Itis obvious, therefore, that the rotary motion received at 23 is transmitted through the medium of the movable convex friction-wheel gearing to the separating-baskets 2.

The central frame for the shaft-bearing of the shafts 1 and 31 is surrounded by an inclined sliding surface 40, which is encircled at its upper part by the fixed cylindrical formed plate 41.

The operation of the invention is as follows:

The raw material is to be separated. For instance, the mash in brewing beer is conducted to the distributing-drum 8 in astrealn through the central opening 42 in the cover 19 and passes fartheralong through the distributingpipes 9 into the lower annular chamber 4 of the separating-baskets 2. While the system rotates quickly about the main shaft 1, the lever 29 is adjusted so that the separatingbaskets 2 do not immediately begin to revolve around their own axes. The mash supplied at 4 is blocked in the separating-baskets under the influence of the centrifugal force at the zone of each separating-basket which is farthest distant from the shaft 1. At the separating-baskets d in Fig. 2 this quantity of liquid is indicated by shade-lines. According to the laws of hydrostatics the liquid will acquirea cylindrical su rface, the vertical axis of which lies parallel to the shaft 1. When the liquid has risen in the single separatingbaskets so far as indicated at (l in Fig. 2, it will commence to dow over at the edge 7, Fig. 1, and spout out through the funnel 18. At this moment the planetary movement of the separating-baskets is to be set in action by means of the lever 29. In the meantime the operationprogresses. Undertheinuence ol' the centrifugal. force the heavier ingredients of the mash, the dratf and starch flour, settle down at the circumference of the separatingbasket. Fresh mash is continually supplied through 9 and let through the annular slits 5 in the baskets, while the cleared wort passes over the edge 7 in a continuous stream to the funnel 18. As the rotation of the separatingbasket 2 progresses the dratf thrown out is gradually led around and approaches the lower vertical edge 15 of the catching-plate 10, so that it finally slips down from the sievewall 6 on account of the centrifugal force (see Fig 2) at d and passes into the interior of the catching-plate 10. On this journey the dratl is nearly completely released of liquid constituents as these find occasion of returning through the perforations of the cellwall 6 to the liquid left back. As mentioned above, a scooping process in the real meaning of the word takes place here. Should the openings of the sieve-surface in 6 be choked during this operation, this would not be -a disadvantage, because the few liquid constituents which are perhaps drawn along iind occasion to ow back from the single scooping-chambers through the slot-openings 5 into the annular space 4 and walls, pass on to that point situated at the greatest distance from the shaft 1, joining again the new material to be separated which comes from the pipe 9. The conical forni of the separatingbasket casing 2 considerably assists the operation described.

In consequence of the new material to be separated passing through slot 5 a certain disturbance or stream is produced in the material exposed to the separating process, and it is obvious that this agitation of the liquid IIO `Will be mostly conspicuous near vthe slot,V l

and the more the liquid vapproaches the edge. 7 the less agitated the stream Will'be, so that the brightness of the cleared wort flowing over at 7 cannot be influenced. f

The draff expelled from the scooping-chambers runs down the sloped catching-plate l y toward the opening .14 at the bottom and gets from hereto the circumference of lthe casing 4l or onto the inclined plane 40l and is removed at foot ofthe machine.
